Yes, yes, the whole “brain swap without surgery” thing. In a rare display of solidarity, Sparks have universally discouraged this particular field of research for two reasons. The first, that science is regarded with enough suspicion as it is, without allowing plausible justification for the whole ‘Is my ruler/boss/lover who I think they are? Or has their mind been replaced by an agent of a secret cabal that is out to get me?’ thing. The second, that it’s really hard to do, and those who manage to successfully pull it off are bloody insufferable about it.
